FIELD OF THE INVENTION

The present invention relates to certain tetrahydro-pyrimidoazepine compounds, pharmaceutical compositions containing them, and methods of using them for the treatment of disease states, disorders, and conditions mediated by TRPV1 activity.

BACKGROUND OF THE INVENTION

Transient receptor-potential (TRP) channel proteins constitute a large and diverse family of proteins that are expressed in many tissues and cell types. One TRP channel protein of particular interest is the vanilloid receptor 1 (TRPV1 or VR1), a non-selective Ca⁺² channel that is the molecular target of vanilloid compounds (e.g., capsaicin and resiniferatoxin). Such vanilloid compounds are known to selectively depolarize nociceptors, specialized primary afferent neurons involved in the signaling pathway that leads to the sensation of pain. TRPV1 is activated by a diverse range of stimuli, including vanilloids, membrane depolarization, heat, stretch, low pH, inflammatory mediators (e.g., lipoxygenase metabolites), and endocannabinoid compounds. Because heightened activity of nociceptors contributes to unwanted pain, inflammatory conditions, thermoregulation, and control of smooth muscle tone and reflexes in mammals, modulation of signaling in this pathway is important in treatment and prophylaxis of various clinical syndromes (Caterina, M. J., Pain 2003, 105(1-2), 5-9; Caterina, M. J. et. al., Annu. Rev. Neurosci. 2001, 24, 487-517; Tominaga, M. et.al., J. Neurobiol. 2004, 61, 3-12; Voets, T. et.al., Nature 2004, 430, 748-754).

Because of TRPV1's connection with the sensory nervous system, TRPV1 agonists and antagonists may be therapeutically useful in the treatment or prophylaxis of disease states, disorders, and conditions mediated by TRPV1 activity, such as: i) pain (e.g., acute, chronic, inflammatory, or neuropathic pain); ii) itch (Kim et al., Neurosci. Lett. 2004, 361, 159) and various inflammatory disorders (Stucky, C. L. et.al., Neuroscience 1998, 84, 1257; Moore, B. A. et.al., Am. J. Physiol. Gastrointest. Liver Physiol. 2002, 282, G1045; Kwak, J. Y. et.al., Neuroscience 1998, 86, 619; Morris, V. H. et.al., Pain 1997, 71, 179; Greiff, L. et.al., Thorax 1995, 50, 225); iii) inner ear disorders (Balaban, C. D. et al., Hear. Res. 2003, 175, 165-70; Zheng, J. et al., J. Neurophys. 2003, 90, 444-55); iv) fever and other disorders or symptoms affected by thermoregulation (Jancso-Gabor et al., J. Physiol. 1970, 206, 495; Swanson et al., J. Med. Chem. 48, 1857; Iida et al., Neurosci. Lett. 2005, 378, 28); v) tracheobronchial and diaphragmatic dysfunction; and vi) gastrointestinal and urinary tract disorders (Lazzeri, M. et al., Eur. Urology 200, 792-798; Apostolidis, A. et.al., Urology 2005, 65, 400-405). Additionally, TRPV1 modulators may be therapeutically useful in the treatment or prophylaxis of anxiety (Marsch, R. et al., J. Neurosci. 2007, 27(4), 832-839); eye-related disorders (such as glaucoma, vision loss, and increased intraocular pressure) (Calkins, D. J. et al., Abstract from ARVO 2006 Annual Meeting, Program #1557, Poster #B93); baldness (e.g., by stimulating hair growth) (Bodo, E. et al., Am. J. Pathol. 2005, 166(4), 985-998); diabetes (including insulin-resistant diabetes or diabetic conditions mediated by insulin sensitivity or secretion) (Razavi, R. et al., Cell 2006, 127(6), 1097-1099; Akiba, Y. et al., Biochem. Biophy. Res. Commun. 2004, 321(1), 219-225).

Acidosis is a well-established feature of cerebral ischaemia. Tissue pH may fall to 6 or lower, sufficient to activate TRPV1 channels expressed in the CNS. TRPV1 antagonists therefore may be useful in the treatment of disorders associated with reduced blood flow to the CNS or CNS hypoxia, such as head trauma, spinal injury, thromboembolic or hemorrhagic stroke, transient ischaemic attacks, cerebral vasospasm, hypoglycaemia, cardiac arrest, status epilepticus, perinatal asphyxia, Alzheimer's disease, and Huntington's Disease.

International Publication No. WO05/014558 (Feb. 17, 2005) describes certain aminopyrimidine inhibitors of voltage-gated sodium and potassium channel. Various bicyclic pyrimidines are disclosed as serotonin receptor modulators in U.S. patent application Ser. No. 11/460,294, filed Jul. 27, 2006. Condensed pyrimidine compounds are disclosed as inhibitors of voltage-gated ion channels in Intl. Publication No. WO 05/014558. Various bicyclic pyrimidines are also disclosed in Intl. Publication No. WO 05/066171 and U.S. Patent Appl. Publ. 2005/0165032 as inhibitors of the TRPV1 channel. However, there remains a need for potent TRPV1 modulators with desirable pharmaceutical properties.

The term “heteroaryl” refers to a monocyclic, fused bicyclic, or fused polycyclic aromatic heterocycle (ring structure having ring atoms selected from carbon atoms and up to four heteroatoms selected from nitrogen, oxygen, and sulfur) having from 3 to 12 ring atoms per heterocycle. Illustrative examples of heteroaryl groups include the following moieties:

and the like.

Those skilled in the art will recognize that the species of cycloalkyl, heterocycloalkyl, and heteroaryl groups listed or illustrated above are not exhaustive, and that additional species within the scope of these defined terms may also be selected.

The term “halogen” represents chlorine, fluorine, bromine or iodine. The term “halo” represents chloro, fluoro, bromo or iodo.

The term “substituted” means that the specified group or moiety bears one or more substituents. The term “unsubstituted” means that the specified group bears no substituents. The term “optionally substituted” means that the specified group is unsubstituted or substituted by one or more substituents. Where the term “substituted” is used to describe a structural system, the substitution is meant to occur at any valency-allowed position on the system. In cases where a specified moiety or group is not expressly noted as being optionally substituted or substituted with any specified substituent, it is understood that such a moiety or group is intended to be unsubstituted.

Any formula given herein is intended to represent compounds having structures depicted by the structural formula as well as certain variations or forms. In particular, compounds of any formula given herein may have asymmetric centers and therefore exist in different enantiomeric forms. All optical isomers and stereoisomers of the compounds of the general formula, and mixtures thereof, are considered within the scope of the formula. Thus, any formula given herein is intended to represent a racemate, one or more enantiomeric forms, one or more diastereomeric forms, one or more atropisomeric forms, and mixtures thereof.

Furthermore, certain structures may exist as geometric isomers (i.e., cis and trans isomers), as tautomers, or as atropisomers. Additionally, any formula given herein is intended to embrace hydrates, solvates, and polymorphs of such compounds, and mixtures thereof.

Any formula given herein is also intended to represent unlabeled forms as well as isotopically labeled forms of the compounds. Isotopically labeled compounds have structures depicted by the formulas given herein except that one or more atoms are replaced by an atom having a selected atomic mass or mass number. Examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine, and chlorine, such as ²H, ³H, ¹¹C, ¹³C, ¹⁴C, ¹⁵N, ¹⁸O, ¹⁷O, ³¹P, ³²P, ³⁵S ¹⁸F, ³⁶Cl, ¹²⁵I, respectively. Such isotopically labeled compounds are useful in metabolic studies (preferably with ¹⁴C), reaction kinetic studies (with, for example ²H or ³H), detection or imaging techniques [such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT)] including drug or substrate tissue distribution assays, or in radioactive treatment of patients. In particular, an ¹⁸F or ¹¹C labeled compound may be particularly preferred for PET or SPECT studies. Further, substitution with heavier isotopes such as deuterium (i.e., ²H) may afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements. Isotopically labeled compounds of this invention and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the schemes or in the examples and preparations described below by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent.

When referring to any formula given herein, the selection of a particular moiety from a list of possible species for a specified variable is not intended to define the moiety for the variable appearing elsewhere. In other words, where a variable appears more than once, the choice of the species from a specified list is independent of the choice of the species for the same variable elsewhere in the formula.

The invention includes also pharmaceutically acceptable salts of the compounds represented by Formula (I), preferably of those described above. Pharmaceutically acceptable salts of the specific compounds exemplified herein are especially preferred.

A “pharmaceutically acceptable salt” is intended to mean a salt of a free acid or base of a compound represented by Formula (I) that is non-toxic, biologically tolerable, or otherwise biologically suitable for administration to the subject. See, generally, S. M. Berge et al., “Pharmaceutical Salts”, J. Pharm. Sci., 1977, 66:1-19, and Handbook of Pharmaceutical Salts, Properties, Selection, and Use, Stahl and Wermuth, Eds., Wiley-VCH and VHCA, Zurich, 2002. Preferred pharmaceutically acceptable salts are those that are pharmacologically effective and suitable for contact with the tissues of patients without undue toxicity, irritation, or allergic response. A compound of Formula (I) may possess a sufficiently acidic group, a sufficiently basic group, or both types of functional groups, and accordingly react with a number of inorganic or organic bases, and inorganic and organic acids, to form a pharmaceutically acceptable salt. Exemplary pharmaceutically acceptable salts include sulfates, pyrosulfates, bisulfates, sulfites, bisulfites, phosphates, monohydrogen-phosphates, dihydrogenphosphates, metaphosphates, pyrophosphates, chlorides, bromides, iodides, acetates, propionates, decanoates, caprylates, acrylates, formates, isobutyrates, caproates, heptanoates, propiolates, oxalates, malonates, succinates, suberates, sebacates, fumarates, maleates, butyne-1,4-dioates, hexyne-1,6-dioates, benzoates, chlorobenzoates, methylbenzoates, dinitrobenzoates, hydroxybenzoates, methoxybenzoates, phthalates, sulfonates, xylenesulfonates, phenylacetates, phenylpropionates, phenylbutyrates, citrates, lactates, γ-hydroxybutyrates, glycolates, tartrates, methane-sulfonates, propanesulfonates, naphthalene-1-sulfonates, naphthalene-2-sulfonates, and mandelates.

If the compound of Formula (I) contains a basic nitrogen, the desired pharmaceutically acceptable salt may be prepared by any suitable method available in the art, for example, treatment of the free base with an inorganic acid, such as hydrochloric acid, hydrobromic acid, sulfuric acid, sulfamic acid, nitric acid, boric acid, phosphoric acid, and the like, or with an organic acid, such as acetic acid, phenylacetic acid, propionic acid, stearic acid, lactic acid, ascorbic acid, maleic acid, hydroxymaleic acid, isethionic acid, succinic acid, valeric acid, fumaric acid, malonic acid, pyruvic acid, oxalic acid, glycolic acid, salicylic acid, oleic acid, palmitic acid, lauric acid, a pyranosidyl acid, such as glucuronic acid or galacturonic acid, an alpha-hydroxy acid, such as mandelic acid, citric acid, or tartaric acid, an amino acid, such as aspartic acid or glutamic acid, an aromatic acid, such as benzoic acid, 2-acetoxybenzoic acid, naphthoic acid, or cinnamic acid, a sulfonic acid, such as laurylsulfonic acid, p-toluenesulfonic acid, methanesulfonic acid, or ethanesulfonic acid, or the like.

If the compound of Formula (I) is an acid, such as a carboxylic acid or sulfonic acid, the desired pharmaceutically acceptable salt may be prepared by any suitable method, for example, treatment of the free acid with an inorganic or organic base, such as an amine (primary, secondary or tertiary), an alkali metal hydroxide, or alkaline earth metal hydroxide, or the like. Illustrative examples of suitable salts include organic salts derived from amino acids, such as glycine and arginine, ammonia, carbonates, bicarbonates, primary, secondary, and tertiary amines, and cyclic amines, such as benzylamines, pyrrolidines, piperidine, morpholine, and piperazine, and inorganic salts derived from sodium, calcium, potassium, magnesium, manganese, iron, copper, zinc, aluminum, and lithium.

In preferred embodiments, the present invention relates to compounds of Formula (I) and to sulfate, hydrochloride, fumarate, tartrate, phosphate, methanesulfonic acid (mesylate), benzenesulfonic acid (besylate), and p-toluensulfonic acid (tosylate) salts thereof.

The invention also relates to treatment methods employing pharmaceutically acceptable prodrugs of the compounds of Formula (I). The term “prgdrug” means a precursor of a designated compound that, following administration to a subject, yields the compound in vivo via a chemical or physiological process such as solvolysis or enzymatic cleavage, or under physiological conditions (e.g., a prodrug on being brought to physiological pH is converted to the compound of Formula (I)). A “pharmaceutically acceptable prodrug” is a prodrug that is not toxic, biologically intolerable, or otherwise biologically unsuitable for administration to the subject. Illustrative procedures for the selection and preparation of suitable prodrug derivatives are described, for example, in “Design of Prodrugs”, ed. H. Bundgaard, Elsevier, 1985.

Exemplary prodrugs include compounds having an amino acid residue, or a polypeptide chain of two or more (e.g., two, three or four) amino acid residues, covalently joined through an amide or ester bond to a free amino, hydroxy, or carboxylic acid group of a compound of Formula (I). Examples of amino acid residues include the twenty naturally occurring amino acids, commonly designated by three letter symbols, as well as 4-hydroxyproline, hydroxylysine, demosine, isodemosine, 3-methylhistidine, norvalin, beta-alanine, gamma-aminobutyric acid, citrulline homocysteine, homoserine, ornithine and methionine sulfone.

Additional types of prodrugs may be produced, for instance, by derivatizing free carboxyl groups of structures of Formula (I) as amides or alkyl esters. Exemplary amides include those derived from ammonia, primary C₁₋₆alkyl amines and secondary di(C₁₋₆alkyl) amines. Secondary amines include 5- or 6-membered heterocycloalkyl or he teroaryl ring moieties. Preferred amides are derived from ammonia, C₁₋₃alkyl primary amines, and di(C₁₋₂alkyl)amines. Exemplary esters of the invention include C₁₋₇alkyl, C₅₋₇cycloalkyl, phenyl, and phenyl(C₁₋₆alkyl) esters. Preferred esters include methyl esters. Prodrugs may also be prepared by derivatizing free hydroxy groups using groups including hemisuccinates, phosphate esters, dimethylaminoacetates, and phosphoryloxymethyloxycarbonyls, following procedures such as those outlined in Adv. Drug Delivery Rev. 1996, 19, 115. Carbamate derivatives of hydroxy and amino groups may also yield prodrugs. Carbonate derivatives, sulfonate esters, and sulfate esters of hydroxy groups may also provide prodrugs. Derivatization of hydroxy groups as (acyloxy)methyl and (acyloxy)ethyl ethers, wherein the acyl group may be an alkyl ester, optionally substituted with one or more ether, amine, or carboxylic acid functionalities, or where the acyl group is an amino acid ester as described above, is also useful to yield prodrugs. Prodrugs of this type may be prepared as described in J. Med. Chem. 1996, 39, 10. Free amines can also be derivatized as amides, sulfonamides or phosphonamides. All of these prodrug moieties may incorporate groups including ether, amine, and carboxylic acid functionalities.

Pharmaceutically active metabolites may also be used in the methods of the invention. A “pharmaceutically active metabolite” means a pharmacologically active product of metabolism in the body of a compound of Formula (I) or salt thereof. Prodrugs and active metabolites of a compound may be determined using routine techniques known or available in the art. See, e.g., Bertolini et al., J. Med. Chem. 1997, 40, 2011-2016; Shan et al., J. Pharm. Sci. 1997, 86 (7), 765-767; Bagshawe, Drug Dev. Res. 1995, 34, 220-230; Bodor, Adv. Drug Res. 1984, 13, 224-331; Bundgaard, Design of Prodrugs (Elsevier Press, 1985); and Larsen, Design and Application of Prodrugs, Drug Design and Development (Krogsgaard-Larsen et al., eds., Harwood Academic Publishers, 1991).

The compounds of Formula (I) and their pharmaceutically acceptable salts, pharmaceutically acceptable prodrugs, and pharmaceutically active metabolites (collectively, “agents”) of the present invention are useful as TRPV1 modulators in the methods of the invention. The agents may be used in the inventive methods for the treatment or prevention of medical conditions, diseases, or disorders mediated through modulation of TRPV1, such as those described herein.

In especially preferred embodiments of the therapeutic methods of the invention, effective amounts of the TRPV1 modulators of the present invention are administered to treat pain, itch, cough, asthma, or inflammatory bowel disease.

The term “treat” or “treating” as used herein is intended to refer to administration of an agent or composition of the invention to a subject for the purpose of effecting a therapeutic or prophylactic benefit through modulation of TRPV1 activity. Treating includes reversing, ameliorating, alleviating, inhibiting the progress of, lessening the severity of, or preventing a disease, disorder, or condition, or one or more symptoms of such disease, disorder or condition mediated through modulation of TRPV1 activity. The term “subject” refers to a mammalian patient in need of such treatment, such as a human. “Modulators” include both inhibitors and activators, where “inhibitors” refer to compounds that decrease, prevent, inactivate, desensitize or down-regulate TRPV1 expression or activity, and “activators” are compounds that increase, activate, facilitate, sensitize, or up-regulate TRPV1 expression or activity.

In treatment methods according to the invention, an effective amount of a pharmaceutical agent according to the invention is administered to a subject suffering from or diagnosed as having such a disease, disorder, or condition. An “effective amount” means an amount or dose sufficient to generally bring about the desired therapeutic or prophylactic benefit in patients in need of such treatment for the designated disease, disorder, or condition. Effective amounts or doses of the agents of the present invention may be ascertained by routine methods such as modeling, dose escalation studies or clinical trials, and by taking into consideration routine factors, e.g., the mode or route of administration or drug delivery, the pharmacokinetics of the agent, the severity and course of the disease, disorder, or condition, the subject's previous or ongoing therapy, the subject's health status and response to drugs, and the judgment of the treating physician. An exemplary dose is in the range of from about 0.001 to about 200 mg of agent per kg of subject's body weight per day, preferably about 0.05 to 100 mg/kg/day, or about 1 to 35 mg/kg/day, or about 0.1 to 10 mg/kg daily in single or divided dosage units (e.g., BID, TID, QID). For a 70-kg human, an illustrative range for a suitable dosage amount is from about 0.05 to about 7 g/day, or about 0.2 to about 2.5 g/day. Once improvement of the patient's disease, disorder, or condition has occurred, the dose may be adjusted for preventative or maintenance treatment. For example, the dosage or the frequency of administration, or both, may be reduced as a function of the symptoms, to a level at which the desired therapeutic or prophylactic effect is maintained. Of course, if symptoms have been alleviated to an appropriate level, treatment may cease. Patients may, however, require intermittent treatment on a long-term basis upon any recurrence of symptoms.

In addition, the agents of the invention may be used in combination with additional active compounds in the treatment of the above conditions. The additional compounds may be coadministered separately with an agent of Formula (I) or included with such an agent as an additional active ingredient in a pharmaceutical composition according to the invention. In an exemplary embodiment, additional active compounds are those that are known or discovered to be effective in the treatment of conditions, disorders, or diseases mediated by TRPV1 activity, such as another TRPV1 modulator or a compound active against another target associated with the particular condition, disorder, or disease. The combination may serve to increase efficacy (e.g., by including in the combination a compound potentiating the potency or effectiveness of an agent according to the invention), decrease one or more side effects, or decrease the required dose of the agent according to the invention. In one illustrative embodiment, a composition according to the invention may contain one or more additional active ingredients selected from opioids, NSAIDs (e.g., ibuprofen, cyclooxygenase-2 (COX-2) inhibitors, and naproxen), gabapentin, pregabalin, tramadol, acetaminophen, and aspirin.

The agents of the invention are used, alone or in combination with one or more other active ingredients, to formulate pharmaceutical compositions of the invention. A pharmaceutical composition of the invention comprises: (a) an effective amount of a pharmaceutical agent in accordance with the invention; and (b) a pharmaceutically acceptable excipient.

A “pharmaceutically acceptable excipient” refers to a substance that is not toxic, biologically intolerable, or otherwise biologically unsuitable for administration to a subject, such as an inert substance, added to a pharmacological composition or otherwise used as a vehicle, carrier, or diluent to facilitate administration of a pharmaceutical agent and that is compatible therewith. Examples of excipients include calcium carbonate, calcium phosphate, various sugars and types of starch, cellulose derivatives, gelatin, vegetable oils, and polyethylene glycols.

Delivery forms of the pharmaceutical compositions containing one or more dosage units of the pharmaceutical agents may be prepared using suitable pharmaceutical excipients and compounding techniques known or that become available to those skilled in the art. The compositions may be administered in the inventive methods by a suitable route of delivery; e.g., oral, parenteral, rectal, topical, or ocular routes, or by inhalation.

The preparation may be in the form of tablets, capsules, sachets, dragees, powders, granules, lozenges, powders for reconstitution, liquid preparations, or suppositories. Preferably, the compositions are formulated for intravenous infusion, topical administration, or oral administration.

For oral administration, the compounds of the invention can be provided in the form of tablets or capsules, or as a solution, emulsion, or suspension. To prepare the oral compositions, the agents may be formulated to yield a dosage of, e.g., from about 0.05 to about 50 mg/kg daily, or from about 0.05 to about 20 mg/kg daily, or from about 0.1 to about 10 mg/kg daily.

Oral tablets may include the agent and any other active ingredients mixed with compatible pharmaceutically acceptable excipients such as diluents, disintegrating agents, binding agents, lubricating agents, sweetening agents, flavoring agents, coloring agents and preservative agents. Suitable inert fillers include sodium and calcium carbonate, sodium and calcium phosphate, lactose, starch, sugar, glucose, methyl cellulose, magnesium stearate, mannitol, sorbitol, and the like. Exemplary liquid oral excipiets include ethanol, glycerol, water, and the like. Starch, polyvinyl-pyrrolidone (PVP), sodium starch glycolate, microcrystalline cellulose, and alginic acid are exemplary disintegrating agents. Binding agents may include starch and gelatin. The lubricating agent, if present, may be magnesium stearate, stearic acid or talc. If desired, the tablets may be coated with a material such as glyceryl monostearate or glyceryl distearate to delay absorption in the gastrointestinal tract, or may be coated with an enteric coating.

Capsules for oral administration include hard and soft gelatin capsules. To prepare hard gelatin capsules, active ingredient may be mixed with a solid, semi-solid, or liquid diluent. Soft gelatin capsules may be prepared by mixing the active ingredient with water, an oil such as peanut oil, sesame oil, or olive oil, liquid paraffin, a mixture of mono and di-glycerides of short chain fatty acids, polyethylene glycol 400, or propylene glycol.

Liquids for oral administration may be in the form of suspensions, solutions, emulsions or syrups or may be lyophilized or presented as a dry product for reconstitution with water or other suitable vehicle before use. Such liquid compositions may optionally contain: pharmaceutically-acceptable excipients such as suspending agents (for example, sorbitol, methyl cellulose, sodium alginate, gelatin, hydroxyethylcellulose, carboxymethylcellulose, aluminum stearate gel and the like); non-aqueous vehicles, e.g., oil (for example, almond oil or fractionated coconut oil), propylene glycol, ethyl alcohol, or water; preservatives (for example, methyl or propyl p-hydroxybenzoate or sorbic acid); wetting agents such as lecithin; and, if desired, flavoring or coloring agents.

The active agents of this invention may also be administered by non-oral routes. For example, the compositions may be formulated for rectal administration as a suppository. For parenteral use, including intravenous, intramuscular, intraperitoneal, or subcutaneous routes, the agents of the invention may be provided in sterile aqueous solutions or suspensions, buffered to an appropriate pH and isotonicity or in parenterally acceptable oil. Suitable aqueous vehicles include Ringer's solution and isotonic sodium chloride. Such forms may be presented in unit-dose form such as ampules or disposable injection devices, in multi-dose forms such as vials from which the appropriate dose may be withdrawn, or in a solid form or pre-concentrate that can be used to prepare an injectable formulation. Illustrative infusion doses range from about 1 to 1000 μg/kg/minute of agent admixed with a pharmaceutical carrier over a period ranging from several minutes to several days.

For topical administration, the agents may be mixed with a pharmaceutical carrier at a concentration of about 0.1% to about 10% of drug to vehicle. Another mode of administering the agents of the invention may utilize a patch formulation to affect transdermal delivery.

Agents may alternatively be administered in methods of this invention by inhalation, via the nasal or oral routes, e.g., in a spray formulation also containing a suitable carrier.

Preferred agents useful in methods of the invention will now be described by reference to illustrative synthetic schemes for their general preparation below and the specific examples that follow. Artisans will recognize that, to obtain the various compounds herein, starting materials may be suitably selected so that the ultimately desired substituents will be carried through the reaction scheme with or without protection as appropriate to yield the desired product. Alternatively, it may be necessary or desirable to employ, in the place of the ultimately desired substituent, a suitable group that may be carried through the reaction scheme and replaced as appropriate with the desired substituent. Unless otherwise specified, the variables are as defined above in reference to Formula (I).

Referring to general Scheme A, compounds of Formula (I) may be prepared from β-ketoesters (VI), where X¹ is a suitable amino protecting group, such as a benzyl or carbamate group. Protected piperidones (V) are commercially available or may be prepared according to known methods. Preferred protecting groups for amines include, tert-butyl carbamate (Boc) or benzyl groups. β-Ketoesters (VI) may be prepared according to general techniques known in the art. For example, β-ketoesters (VI) may be accessed from piperidones (V) by ring expansion of piperidones (V) with ethyl diazoacetate in the presence of a Lewis acid, such as BF₃.OEt, in a suitable solvent, such as Et₂O or CH₂Cl₂ or a mixture thereof, at temperatures ranging from about 0° C. to about room temperature (rt). β-Ketoesters (VI) may be reacted with amidines or carboximidamides (VII), or with ureas or thioureas (VIII), for example, in the presence of NaOEt or KOtBu, in a solvent such as EtOH or tBuOH or a mixture thereof, at temperatures between rt and the reflux temperature of the solvent, to form hydroxy pyrimidines (IX). Where the condensation is done-with a urea or thiourea, in situ alkylation with an alkyl chloride or bromide provides pyrimidines (IX) where R¹ is —S—C₁₋₆alkyl or —O—C₁₋₆alkyl. The X¹ protecting group may be removed using known methods. For example, a Boc group may be removed with an acid such as TFA or HCl, in a solvent such as Et₂O, dioxane, EtOH, or MeOH or a mixture thereof, to form amines (IX) where X¹=—H. Where an acid salt is obtained, the corresponding free base may be obtained by suitable general methods known in the art. Preferably, the free base is obtained by filtration of the salt through resin-bound carbonate using an alcoholic solvent, preferably MeOH. Where X¹ is a benzyl group, the group may be removed according to standard methods, such as hydrogenation in the presence of a palladium catalyst such as Pd/C or Pd(OH)₂/C, in a solvent such as EtOH. Hydroxy pyrimidines (IX) where X¹ is —H may then be converted to amines (X) using known methods such as S_(N)-aryl substitution, or palladium-mediated cross-couplings. S_(N)-Aryl substitution may be accomplished by treatment of hydroxy pyrimidines (XI), where X¹ is —H, with Ar-HAL (where HAL is halo), such as 2-chloro-3-trifluoromethyl-pyridine, in the presence of a base such K₂CO₃, in a polar solvent such as DMSO, at temperatures between about rt and the reflux temperature of the solvent. Palladium-mediated cross-couplings are done by reacting Ar-HAL in the presence of a palladium catalyst. Preferably, hydroxy pyrimidines (IX), where X¹ is —H, are treated with Et₃N or (iPr)₂NEt, in suitable solvents, such as n-BuOH, tBuOH, t-amyl alcohol, DMF, DMSO, DME, or NMP, or a mixture thereof, at temperatures from about 100 to about 200° C. Pyrimidines (X) can then be activated for use in palladium-mediated cross-coupling reactions or S_(N)2 reactions by general procedures known in the art. For example, treatment with POCl₃, PCl₃, PBr₃, or POBr₃ affords the corresponding halopyrimidines (XI) where Z is chloride or bromide. Treatment of pyrimidines (X) with trifluoromethane-sulfonic anhydride or N-phenyl-bis(trifluoromethanesulfonimide) in DCE, CH₂Cl₂, or THF, or a mixture thereof, in the presence of a base such as pyridine, Et₃N, (iPr)₂NEt, or KOtBu, provides triflates (XI) where Z is —OSO₂CF₃. In a preferred embodiment, pyrimidines (X) are treated with POCl₃ in CH₃CN at temperatures from about 80 to about 100° C.

Substitution of pyrimidines (XI) with amines HN(R²)R³ to produce compounds of Formula (I) may be accomplished by various suitable methods within the routine purview of artisans. Where Z is Cl, substitution may involve heating chloro-pyrimidines (XI) with suitable amines (XII) in alcoholic solvents such as MeOH, EtOH, tBuOH, n-BuOH, or t-amyl-OH, or a mixture thereof, at temperatures from about rt to about the reflux temperature of the solvent. Preferably, the solvent is n-BuOH and the temperature is about 130° C. Alternatively, chloro-pyrimidines (XI) may be reacted with amines (XII) in the presence of an acid catalyst, preferably p-toluenesulfonic acid or TFA, in toluene or dioxane, at temperatures from about 100 to about 150° C., to provide compounds of Formula (I). Coupling of halides or triflates (XI) with amines (XII), in the presence of a catalyst such as Pd(OAc)₂, Pd(PPh₃)₄, PdCl₂(PPh₃)₂, or PdCl₂(Po-tol₃)₂, in a solvent such as THF, 1,4-dioxane, DMA, DMF, DME, or toluene, or mixtures thereof, in the presence of a base such as NaOtBu, Na₂CO₃, K₂CO₃, Cs₂CO₃, or K₃PO₄, with or without an additive such as 2-(dicyclohexylphosphanyl)biphenyl (DCPB), also affords pyrimidines (I). In a preferred embodiment, coupling is accomplished in the presence of Pd(OAc)₂ catalyst, DCPB, and NaOtBu in toluene at temperatures from about 100 to about 200° C. in a microwave reactor.

Referring to Scheme B, compounds of Formula (I) may be prepared by an alternate general route. Protected piperidones (XV), such as 1,4-dioxa-8-aza-spiro[4,5]decane (where PG is —O—(CH₂)₂—O—), may be converted to aryl amines (XIV) by S_(N)-aryl substitution or palladium-mediated cross-couplings as described in Scheme A. Deprotection of the protecting group using known general procedures, such as concentrated HCl, provides ketones (XV). Ketones (XV) may be processed into compounds of Formula (I) generally according to the ring expansion, condensation, activation, and displacements described in Scheme A.

Referring to Scheme C, thioethers (XVI), obtained as described in Scheme A, may be oxidized using generally known methods to provide sulfones (XVII). Displacement of the sulfone substituent is attained by reaction with alcohols HO—C₁₋₆alkyl or amines HN(R^(a))R^(b) in solvents such as MeOH, EtOH, n-BuOH, THF, DMF, DMSO, or toluene, or a mixture thereof, with or without the presence of a suitable base, such as NaOMe, NaOEt, KOtBu, NaH, Et₃N, (iPr)₂EtN, or pyridine, at temperatures between rt and the reflux temperature of the solvent. Preferably, displacement with amines HN(R^(a))R^(b) is performed by heating with sulfones (XVII) in toluene in a sealed tube at 110° C.

Compounds of Formula (I) may be converted to their corresponding salts using methods known to those skilled in the art. For example, amines of Formula (I) may be treated with trifluoroacetic acid, HCl, citric acid, H₂SO₄, methanesulfonic acid (MsOH), benzenesulfonic acid, or p-toluenesulfonic acid (TsOH) in a solvent such as Et₂O, EtOAc, CH₂Cl₂, THF, or MeOH, or a mixture thereof, to provide the corresponding salt forms.

Compounds prepared according to the schemes described above may be obtained as single enantiomers, diastereomers, or regioisomers, or as racemic mixtures or mixtures of enantiomers, diastereomers, or regioisomers. Where regioisomeric or diastereomeric mixtures are obtained, isomers may be separated using conventional methods such as chromatography or crystallization. Where racemic (1:1) and non-racemic (not 1:1) mixtures of enantiomers are obtained, single enantiomers may be isolated using conventional separation methods known to one skilled in the art. Particularly useful separation methods may include chiral chromatography, recrystallization, diastereomeric salt formation, or derivatization into diastereomeric adducts followed by separation.

The following examples are provided to further illustrate aspects of the invention and various preferred embodiments.

Intermediate H: 2-(4-Amino-phenyl)-2-methyl-propionic acid methyl ester

Step A: 2-Methyl-2-(4-nitrophenyl)-propionic acid methyl ester. To a solution of 2-methyl-2-(4-nitrophenyl)-propionic acid (1.0014 g, 4.76 mmol) in 10% MeOH/benzene (20 mL) was added dropwise (trimethylsilyl)-diazomethane (2.0 M in hexanes, 3.5 mL, 7.0 mmol). The reaction mixture was stirred at rt until evolution of N₂ ceased (<5 min) and then concentrated. The crude residue was purified (FCC) to give the title compound (937.6 mg, 88%).

Step B. To a solution of 2-methyl-2-(4-nitrophenyl)-propionic acid methyl ester (932.2 mg, 4.16 mmol) and ammonium formate (1.58 g, 25.1 mmol) in MeOH was added Pd/C (10%, 441.2 mg, 0.414 mmol). The reaction mixture was stirred at rt until gas evolution ceased, then filtered through a plug of diatomaceous earth and concentrated. The residue was redissolved in H₂O and extracted with EtOAc. The organic layers were combined, dried, and concentrated to provide the title compound which was used without further purification.

Assay: Block of Capsaicin-induced Ca²⁺ Influx A. Human Assay

HEK293 cells were transfected with human TRPV1 cloned in pcDNA3.1zeo(+) using the Effectene non-liposomal lipid based transfection kit (Qiagen) (hTRPV1/HEK293). hTRPV1/HEK293 cells were routinely grown as monolayers under selection in zeocin (200 μg/mL; Invitrogen) in Dulbecco's Modified Eagle Medium (DMEM, Gibco BRL) supplemented with 10% fetal bovine serum, and penicillin/streptomycin (50 units/mL) in 5% CO₂ at 37° C. Cells were passaged frequently, every 3-5 days, to avoid overgrowth, depletion of essential medium components, or acidic medium exposure. Cells were passaged using a brief wash in 0.05% trypsin with 1 mM EDTA, followed by dissociation in divalent-free phosphate-buffered saline (Hyclone #SH30028.02). Dissociated cells were seeded onto poly-D-lysine coated black-walled 96-well plates (Biocoat; Becton Dickinson #354640) at about 40,000 cells per well and grown for approximately 1 day in culture medium to near confluency. The assay buffer was composed of 130 mM NaCl 2 mM KCl, 2 mM MgCl₂, 10 mM HEPES, 5 mM glucose, and either 2 mM or 20 μM CaCl₂. On the day of the experiment, the culture medium was replaced with 2 mM calcium assay buffer using an automated plate washer (ELx405; Biotek, VT). The cells were incubated in 100 μL/well Fluo-3/AM (2 μM; TEFLabs #0116) with Pluronic F₁₂₇ (100 μg/mL; Sigma #P2443) for 1 h at rt in the dark. After loading the cells, the dye solution was replaced with 50 μL/well of 20 μM calcium assay buffer using the ELx405 plate washer. Test compounds (50 μL/well) were added to the plate and incubated for 30 min. Intracellular Ca²⁺ levels were subsequently assayed using a Fluorometric Imaging Plate Reader (FLIPR™ instrument, Molecular Devices, CA) to simultaneously monitor Fluo-3 fluorescence in all wells (λ_(excitation)=488 nm, λ_(emission)=540 nm) during challenge with agonist (capsaicin). The IC₅₀ values were determined. Cells were challenged with 150 nM capsaicin and the fluorescence counts were captured following agonist addition at a sampling rate of 0.33 Hz. The contents of the wells were mixed 3 times (40 μL mix volume) immediately after the additions were made. Concentration dependence of block was determined by exposing each well of cells in duplicate rows of a 96 well plate to a serial dilution of test compound. The concentration series usually started at 10 μM with a three-fold serial decrement in concentration. The magnitude of the capsaicin response was determined by measuring the change in fluo3 fluorescence before and 100 seconds after the addition of the agonist. Data were analyzed using a non-linear regression program (Origin; OriginLab, MA). Results for the compounds tested in this assay are presented in Table 1. IC₅₀ values shown are the average (mean) of the results obtained.

B. Rat Assay

The assay was performed as described above, using HEK293 cells transfected with rat TRPV1 (rTRPV1/HEK293). These cells had a geneticin selection marker and were grown in Dulbecco's Modified Eagle Medium (DMEM, Gibco BRL) supplemented with 10% fetal bovine serum, penicillin/streptomycin (50 units/mL), and 500 μg/mL genetecin 5% CO₂ at 37° C. Results for the compounds tested in this assay are also presented in Table 1. IC₅₀ values shown are the average (mean) of the results obtained. Where activity is shown as greater than (>) a particular value, the value is the solubility limit of the compound in the assay medium.
